Safari 503 slow downloads

Just bought a new Imac, safari's downloads are really slow, sometimes down to 2kbs
Firefox is up to 320kbs. What gives!
Thanks, CM

I'm having the same problem. I'm writing this from my PC using Explorer because the performance is TERRIBLE on my new MAC Mini running Safari. Even worse, I bought the MAC Mini to replace this PC. The PC performance is fine on the same network connection.

Safari not slowing downloads. Help!

Why does safari not allow downloads. I am trying to download Microsoft office and it wil not allow it. Any suggestions?

Hello,
No, Microsoft Office is for Mac (Office 2011) running OS X, not iOS (which is what runs on the iPad and iPhone).
To open and edit Office documents, I recommend DataViz Documents to Go (http://www.dataviz.com).

Safari very slow downloading files

When I bought my MacBook Pro in 2009 I used Safari for few days then I switched to Firefox, and the reason for that is that downloading any kind of files goes very slow to around 5 KB/s while downloading the same file in any other browser is so fast. Now after the release of Safari 4 I thought this problem could be solved but here again the exact same problem and I really love the new safari except that this problem is really annoying me. By the way browsing is working perfectly fine.
I have a 2 Mpbs ADSL connection.
any idea?

Preference files retain information about the default and custom settings for a particular application. Also, they store information accumulated over time not directly related to a preference setting.
In Safari's case, this retained and accumulated information comes from a variety of sources within and outside of Safari. For example, 3rd party add-ons, such as Glims, store information in the preference file pertinent to their operation and settings.
Sometimes, corruption occurs if this information is incorrectly coded in the software. In that instance, as Safari accesses the preference file, it will crash due to a flaw in the data stream. Another example - updating Safari from one version to the next might trigger corruption if the 3rd party content within the preference file is not compatible with the new version's operation.

2.Power off the router. Wait awhile. Power it back on. Wait until all the lights are lit up properly.
   It will take a while.
   Restart the computer.
3.Start up in Safe Mode

Safari too slow - help finding a bug?

Hi all,
Sorry for such a noob question, this is a problem I never have myself. My wife's iMac (10.4) is running Safari extremely slow. This occurred when we were out of town and our inlaws were house-sitting.
My inlaws have been known to (inadvertently) change settings and download things they should not. (Flash players or radio listening programs, etc). I'm betting something similar happened, but couldn't find anything in the surfing history since it was too much to go through. Other ideas?
Ran Onyx and all that is clean, btw. I've never needed any other anti-malware software myself...
(As a sidenote, would upgrading to 10.5 make a difference?) I have an unopened copy of Leopard - Server (I don't need the server part) at my disposal. What needs to happen for that?
Thanks so much,
-josh

HI,

Very Slow Download Speed

Hi,
I am experiencing very slow downloading speeds, when I am just normally downloading something in Safari, or downloading a torrent with upto 100 seeders.
The maximum download speed I have seen on my computer is 80kb/s, which is painfully slow for downloading the Adobe trials, when they reach about 1gb.
I have a router, connected to 2 computers, and speedtest.net has told me that my download speed is 1mb/s.
It seems like download speeds are being restricted to 80kb/s, so is there any way to 'unlock' full potential downloading speeds?
Any help much appreciated!
-Ollie

I think you're making the same mistake a lot of people make.
The maximum download speed I have seen on my computer is 80kb/s
Safari reports downloads in kiloBYTES per second, not kilobits, so that 80KB/s translates to about 640 kilobits per second.
downloading the Adobe trials, when they reach about 1gb
Really? 1 gigabit per second? I assume that's a typo.
speedtest.net has told me that my download speed is 1mb/s
therefore your downloads are progressing at about 64% of maximum. That sounds about right - you won't get maximum throughput for every download - it will vary based on server location, network load and more.

Videos won't stream (eg youtube) and safari very slow

Hi, I have 2 problems and would really appreciate any help
1 - safari very slow to open pages and has been like this for weeks. I have seen a solution to change to 'opendns' under System preferences > network > advanced tab but I cannot see an option for that. I think this may be my problem as Google always opens quickly. Can anyone elaborate on this solution?
2 - Videos won't stream and just hang with circle (e.g on sites like youtube) which started about 1 week ago. Only thing I have done differently is watching megavideos on unknown site. I have tried the solutions given under other threads (e.g. deleting cache files and uninstalling and reinstalling adobe flash). This seemed to help slightly the first time I tried it but still took approx 60s to stream 1 minute video. Has now reverted back to not streaming.

To set up a test account, open System Preferences > Accounts, click on the padlock icon to unlock it, then click on the "+" sign, name the account "test" and leave the password field blank, since you don't need the account that long; you can delete it later.
Quit System Preferences, log out of the regular user account and into the test account, then try using Safari to load pages and videos to see if the problem continues there.
Other things you can try in your regular user account that may help your problem or solve it are this:
1. Go to Home/Library/Caches/com.apple.Safari and delete the contents of that folder.
2. Go to Home/Library/Caches/com.apple.Safari/Web Page Previews and delete the contents of that folder.
3. If you don't want to use the Top Sites or Cover Flow features, open Terminal and paste in this command:
defaults write com.apple.Safari DebugSnapshotsUpdatePolicy -int 2
then press Enter or Return and quit Terminal
4. Go to Home/Library/Caches/Metadata/Safari and delete the contents of that folder.
5. Go to Home/Library/Caches/Safari and delete the contents of that folder.
6. Go to Home/Library/Safari and delete these files (if you have them):
Downloads.plist
History.plist
Form Values
LastSession.plist
WebpageIcons.db
Then Repair Permissions, restart Safari and see if the speed is improved.

Safari could not download the file because there is not enough disk spacr

safari could not download the file because there is not enough disk space I have a 1TB hard drive and only use a small amout of space.Mac os x mountain lion (12.8.2), HD 978.59 free out of 999.35GB.Please help Brenton

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.
Test while in safe mode. Same problem?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

Extremely slow download speeds and internet browsing on Macbook pro

I recently got a 13"" macbook pro. System config - Maverick OS/i7 dual core/8GB RAM/750 GB HDD, Almost 690GB of free space available. I am expriencing extremely slow download and internet browsing speed. I have to wait for almost 10-12 seconds for normal sites to download. The app updates and downloads are painstakingly slow.
The internet speeds are working perfectly fine on my Windows Laptop, and even on my mobile phones. So, the there's no issue of network. Also, I have cleared safari cache etc, just to be sure. But nothing's really helping.
Can any one help me here.
Thanks !

Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If the answer is no, do that now and see whether there's any change.
Quit and relaunch the browser. Any change?
Log out and log back in. Any change?
Enable Private Browsing in the Safari menu. Any change?
Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
Again, if only Safari is involved, open the iCloud preference pane and uncheck the box marked Safari, if it's checked. Any change?
Are there any other devices on the same network that can browse the Web, and are they affected?
If you can test Safari on another network, is it the same there?
If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

I have a brand new iphone 4. facebook and safari are slow. Is this the settings or the does the phone have a problem?

Safari 4 slow, crash, shutdown problems? Three solutions to try...

There are many posts addressing Safari 4's slowness and worse. I had these problems and cured them with three fixes:
1. Empty Cache periodically - Still tried and true. For me, a blank screen trying to load is the cue to empty cache - page then pops.
2. Turn off Top Sites. This "enhancement" consumes time and takes hard drive space. Someone suggested turning it off and then getting rid of the files (not folders) it had set aside. (They are located in home/Library/Caches/com.apple.Safari/Webpage Previews.) I found almost 3,000 files consuming about 600 MB residing there! They are simply saved web pages, so no hidden risks from deleting them. The next thing to do is keep Safari from saving new webpages. I found the simplest solution is to click on "Website Previews," then Get Info and change permission to "Read Only." I did these Top Sites actions in July. It really helped and I've had no problems.
Then, my Safari started slowing down again, frequently getting hung up (requiring Force Quit), and even crashing. Also, my computer was running hot. I turned on Activity Monitor in the Dock with CPU usage showing and saw the CPU was being driven up to 100% by some websites. Businessweek.com became my test site because it was so slow and invariably crashed Safari after a short while. The key seemed to be the number of Flash videos a webpage was trying to load, so I started a search for a cure. That led me to...
3. Install ClickToFlash (http://rentzsch.github.com/clicktoflash/). You can find others who have recommended it in the Apple discussions and elsewhere. Easy to download, it's unobtrusive and IT WORKS! Now, those Business Week pages load quickly with four(!) little white boxes labeled "Flash". There is a gear that gives you options: load flash, load all on this page, add -site- to whitepage (meaning always load flash on this website - this whitepage list can be edited), and ClickToFlash settings. It's quick and easy to turn on a flash. Now, my Activity Monitor hardly moves, and my computer runs cool.
Hope these help for you. For me, these solutions have cured my Safari problems - at least until Apple releases a new upgrade or version.

Fix for Safari 5 Slowness

I've been looking around many forums and I've noticed many people, like myself, noticed a slow Safari 5 on Mac and that the scrolling was poor etc. I even resorted to using Chrome because Safari was slow, kept beachballing and crashing.
The culprit I found (on my Mac) was Flash Player 10.1. So i decided to uninstall this and reinstall - it made no difference. Therefore I decided to downgrade and there you go, original Safari speed, smoothness and stability returned. I've gone from Flash Player 10.1 down to 10.
1. First download the appropriate uninstaller listed on this page http://bit.ly/PW3xO corresponding with the operating system installed.
2. Run the uninstaller so that there is no Flash Player left on your Mac.
3. Then download Flash Player 10 for Mac http://kb2.adobe.com/cps/142/tn_14266.html
4. Load the Dmg file and follow the installer.
5. Now if like me, you should have the same results!
If it doesn't work, im sorry but it worked for me so it may work for some of you!
Good Luck!
<Link Edited by Host>

Hi, welcome... and thanks for the tip - a few people have done the same thing here.
You might find the moderators don't like the link to Flash that people don't know the source of...
so I'll say that older Flash versions can be downloaded straight from adobe at http://kb2.adobe.com/cps/142/tn_14266.html although it's a 157MB zip archive.
Flash 10..0.x may also be extracted from the recent combo & some other updates, using Pacifist from http://charlessoft.com/ it's free to use/try out.

Safari is slow/I give up

I give up. Safari is slow at loading other sites if it loads at all. A different browser has NO PROBLEMS loading!!

Greetings,
Safari is not slow at all; the problem is with your system. Instead of complaining, try this:
1. Go to Home/Library/Cookies and delete the Cookies.plist file.
2. Go to Home/Library/Caches/com.apple.Safari and delete the contents of that folder.
3. Go to Home/Library/Caches/com.apple.Safari/Web Page Previews and delete the contents of that folder.
4. If you don't want to use the Top Sites or Cover Flow features, open Terminal and paste in this command:
defaults write com.apple.Safari DebugSnapshotsUpdatePolicy -int 2

7. Go to Home/Library/Safari and delete these files (if you have them):
Downloads.plist
History.plist
